Question

20 gram of HNO3 in 1.0 litre of an aqueous solution molarity of the following solution​

Answer 1

Answer:

0.317M

Explanation:

you have to calculate the number of moles in 20g  of HNO3. moles can be calculated from mass and molecular mass of the acid. molecular mass of acid is obtained by summing the RAM of the component atoms. in HNO3 we have H= 1, N= 14 and O=6, molecular mass of HNO3 = (1+14+16*3)= 63. moles is egual to mass divided by molar mass = 20/63 giving 0.317 moles.

this moles are in 1 litre   of solution. molarity is defined as moles per litre this gives 0.317moles/litre = 0.317M
