Step 1

The value is given as follows:

Step 2

The ratio between mass of compound and its molecular mass is considered as number of moles which can be represented as gfollows:

Step 3

Substitute the given values into the formula of moles in... help_outlineImage TranscriptioncloseSince, molar mass of HNO, = 63.01 g Now 19.6mol= mass of HNO, 63.01 g/mol 19.6 mol x 63.01 g/mol 1235 g mass of HNO fullscreen
