An atom has a mass number of 30 and 16 neutrons. What is the atomic number of this atom?
Lana71 [14]
The mass number is the number of protons plus the number of neutrons. Since there are 16 neutrons, there are 14 protons. This also corresponds to the atomic number, so this atom's atomic number is 14 which is also Silicon

The molecular weight of a gas that has a density of 5.75 g/l at stp is __________ g/mol.
Ira Lisetskai [31]

Answer : The molecular weight of a gas is, 128.9 g/mole

Explanation : Given,

Density of a gas = 5.75 g/L

First we have to calculate the moles of gas.

At STP,

As, 22.4 liter volume of gas present in 1 mole of gas

So, 1 liter volume of gas present in \frac{1}{22.4}=0.0446 mole of gas

Now we have to calculate the molecular weight of a gas.

Formula used :

\text{Moles of gas}=\frac{\text{Mass of a gas}}{\text{Molecular weight of a gas}}

Now put all the given values in this formula, we get the molecular weight of a gas.

0.0446mole=\frac{5.75g}{\text{Molecular weight of a gas}}

\text{Molecular weight of a gas}=128.9g/mole

Therefore, the molecular weight of a gas is, 128.9 g/mole
