<u>Answer:</u> The mass of hydrogen gas is 12 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of hydrogen gas = 2 g/mol

Moles of hydrogen gas = 6.0 moles

Putting values in above equation, we get:

6.0mol=\frac{\text{Mass of hydrogen gas}}{2g/mol}\\\\\text{Mass of hydrogen gas}=(6.0mol\times 2g/mol)=12g

Hence, the mass of hydrogen gas is 12 grams

Mass = moles x molar mass
so mass of 6 moles of h2 is: 6×1×2 = 12g

What is the majority of 0.50 g of na dissolved in a 1.5 L solution
Oxana [17]

The correct answer is 0.014467 M.  

Molarity is defined as the number of moles present in a liter solution, that is, number of moles / liter solution.  

The molar mass of sodium (Na) is 23.0 g/mol

Thus, 1 mole of Na contains 23.0 g

Now, x moles of Na contains 0.50 g

Moles = 0.50 × 1 / 23.0

Moles = 0.50 / 23.0  

= 0.0217 moles of Na

Molarity = Number of moles / liters of solution

= 0.0217 / 1.5

= 0.014467 M
