Answer:
The molar mass of the gas is 44 g/mol
Explanation:
It is possible to solve this problem using Graham's law that says: Rates of effusion are inversely dependent on the square of the mass of each gas. That is:
If rate of effusion of nitrogen is Xdistance / 48s and for the unknown gas is X distance / 60s and mass of nitrogen gas is 28g/mol (N₂):
6,61 = √M₂
44g/mol = M₂
<em>The molar mass of the gas is 44 g/mol</em>

Ca2+ and Cl- are examples of ions. There are two types of ions: (1) the positively charged which are called cations and (2) negatively charged which are more commonly referred to as anions.
The charges of the ions identify their reactions with other ions. Like charges do not react and repel each other while unlike charges will attract. Hence, in this item, the ions will attract each other. Further, the reaction between this two ions will form a formula unit, CaCl2.
Answer:
using the formula of numbers of molecules
Explanation:
mass /Mr 44/44=1 molecules of carbon dioxide present
(Mr of carbon dioxide is ( 2*16)+12=44
Now time by Abogadros constant 1*6.002*10^23
molecules of CO2 are present = 6.002*10^23
