At 393 K, the pressure of a sample of nitrogen is 1.07 atm. What will the pressure be at 478 K, assuming constant volume?
True [87]

Answer:

About 1.301 atm

Explanation:

The formula that you should is PV=nRT, where P stands for pressure, V stands for volume, n stands for the number of moles, R stands for the universal gas constant, and T stands for temperature in Kelvin. Since the volume, number of moles, and universal gas constant don't change, you don't need to worry about them.

1.07V=393nR

PV=498nR

P=1.301 atm. Hope this helps!

Q #13 How many moles of MgCl2 are there in 350. g of compound?
Vaselesa [24]

<u>Answer:</u>

3.67 moles

<u>Step-by-step explanation:</u>

We need to find out the number of MgCl_2 moles present in 350 grams of a compound.

Molar mass of Mg = 24.305

Molar mass of Cl_2 = 35.453

So, one mole of MgCl_2 = 24.305 + (35.453 * 2) = 95.211g

1 Mole in 1 molecule of MgCl_2 = \frac{1}{95.211} = 0.0105

Therefore, number of moles in 350 grams of compound = 0.0105 * 350

= 3.67 moles
