Because of the crystal structure of the ice, ice has lower density than liquid water. So the volume of the ice of same mass is greater than water. When melting, the volume will decrease.
<u>Answer:</u> The molar mass of the gas is 35.87 g/mol.
<u>Explanation:</u>
To calculate the mass of gas, we use the equation given by ideal gas:
PV = nRT
or,

where,
P = Pressure of gas = 945 mmHg
V = Volume of the gas = 0.35 L
m = Mass of gas = 0.527 g
M = Molar mass of gas = ? g/mo
R = Gas constant = 
T = Temperature of gas = ![88^oC=[88+273]=361K](https://tex.z-dn.net/?f=88%5EoC%3D%5B88%2B273%5D%3D361K)
Putting values in above equation, we get:

Hence, the molar mass of the gas is 35.87 g/mol.
Answer:
It would take 9.54 x 10^15 years to count 1 mole of atoms which is 10^6 times the age of Earth.
