Find the :
weight of 0.2 mole of `H_(2)` gas

Text Solution

AI Generated Solution

To find the weight of 0.2 moles of \( H_2 \) gas, we can follow these steps: ### Step 1: Determine the Molar Mass of \( H_2 \) The molar mass of a substance is the mass of one mole of that substance. For \( H_2 \) gas, which consists of two hydrogen atoms, we first need to find the atomic mass of hydrogen. - The atomic mass of hydrogen (H) is approximately 1 gram/mole. - Since \( H_2 \) contains two hydrogen atoms, the molar mass of \( H_2 \) is: \[ ...
