Answer:
The volume is the same for any gas.
Explanation:
<em>Which describes the volume of 1 mol of gas at standard temperature and pressure?
</em>
- <em>The volume is greater for a larger mass of gas.</em> FALSE. The volume depends on the amount of matter (moles) and not on the mass.
- <em>The volume is the same for any gas.
</em> TRUE. The volume of any gas at standard temperature and pressure is 22.4 L.
- <em>The volume depends on the size of the container.</em> FALSE. The volume is constant at fixed moles, pressure and temperature.
- <em>The volume varies with the pressure.</em> FALSE. The standard pressure is 1 atm and it is constant.
C3H8 -----> 3 CO2 (from equation)
1mol C3H8 ------ 3 mol CO2
2.0 mol C3H8 ---- x mol CO2
x=(2.0 mol C3H8* 3 mol CO2)/1mol C3H8 =6 mol CO2
Ans: 383.5 grams
383.5 grams is the mass of water should be added to 22.0 g of KCl to make a 5.50 % by mass solution.
