The product of the measurements 2.05 cm x 32 cm should be rounded to

Chemistry
1 answer:
Bas_tet [7]3 years ago
7 0

Answer:

Two significant figures

Step-by-step explanation:

In <em>multiplication </em>problems, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.

2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)

There are three significant figures in 2.05, but only two in 32.

You must round to <em>two</em> significant figures and report the answer as 66 cm².

65.600 000 00 cm² ⟶ 66 cm²

A 7.12 L cylinder contains 1.21 mol of gas A and 4.94 mol of gas B, at a temperature of 28.1 °C. Calculate the partial pressure
GenaCL600 [577]

Answer:

P_A=4.20atm\\\\P_B=17.1atm

Explanation:

Hello!

In this case, since the equation for the ideal gas is:

PV=nRT

For each gas, given the total volume, temperature (28.1+273.15=301.25K) and moles, we can easily compute the partial pressure as shown below:

P_A=\frac{n_ART}{V} =\frac{1.21mol*0.082\frac{atm*L}{mol*K}*301.25K}{7.12L} \\\\P_A=4.20atm\\\\P_B=\frac{n_BRT}{V} =\frac{4.94mol*0.082\frac{atm*L}{mol*K}*301.25K}{7.12L} \\\\P_B=17.1atm

Best regards!
