The markers are transfered in the order given (with bio transferring first), but the first three genes are very close together. Exconjugants are plated on a medium containing str (streptomyacin to counterselect Hfrcells), amp (ampicillin), glu (glutamine) and bio (biotin). The following results are obtained for 400 colonies from thee plates isolayted and tested for growths on various media.

1) amp only 351

2) amp, glu 360

3) amp, bio 380

4) amp, glu, and bio 400

Assume all temperatures to be exact.
In an experiment, a 0.190-kg piece of a ceramic material at 30 C isplaced in liquid nitrogen at its boiling point to cool in aperfectly insulated flask, which allows the gaseous N_2 toimmediately escape.

A:How many liters of liquid nitrogen will be boiled away duringthis operation? (Take the specific heat of the ceramic material tobe that of glass and the density of liquid nitrogen to be 0.80 ×10^3 kg/m^3 .)

V=? L

A 20.0 g copper ring at 0.000°C has an inner diameter of D =2.54000 cm. An aluminum sphere at 93.0°C has a diameter of d =2.54508 cm. The sphere is placed on top of the ring, and the twoare allowed to come to thermal equilibrium, with no heat lost tothe surroundings. The sphere just passes through the ring at theequilibrium temperature, and the coefficients of linear expansionof aluminum and copper are αAl = 23 10-6/C° and αCu = 17 10-6/C°,respectively. . What is the mass of the sphere?
1 kg


MY ANS WAS : 0.001302821 kgand was wrong

NOTE:

Did you use the equation for linear expansion for the ball and alsofor the ring so that the ball ends up with a radius equaling theinner radius of the ring? You then know the final temperature andthus also the temperature for each object. How much energy isgained by the ring? How much is lost by the ball? Can you then usethe expression relating energy loss to mass, specific heat, andtemperature change?

1 ) In a physics lab, a student accidentally drops a 27.0-g brasswasher into an open Dewar of liquid nitrogen at 77.2 K. How muchliquid nitrogen boils away as the washer cools from 297 K to 77.2K? The latent heat of vaporization for nitrogen is 199.1kJ/kg.

2 ) What mass of water at 28.0° C added to a Styrofoam cupcontaining two 60.0-g ice cubes from a freezer at -20.0° C willresult in a final temperature of 5.0° C for the drink?

3 ) Ice at 0.0° C is mixed with 4.00 102 mL of water at 21.0° C.How much ice must melt to lower the water temperature to 0.0° C?

An aluminum bolt has a mass of 114 g, and its temperature is 30.0 oC. The bolt is dropped into a large tank of liquid nitrogen, whose temperature is -195.8 oC. Assuming no heat exchange with the surrounding, how much nitrogen boils away as the bolt reaches thermal equilibrium with the liquid nitrogen?

In an experiment, a 0.150 kg block piece of ceramicsuperconducting material at 20°C is placed in liquid nitrogen atits boiling point to cool in a perfectly insulated flask, whichallows the gaseous N2 immediately to escape. How many liters ofliquid nitrogen will be boiled away in doing this operation? (Takethe specific heat of the ceramic material to be the same as that ofglass, and take the density of liquid nitrogen to be800kg/m³)

Answer: 0.17 Liters
