62. Calculate the mass of a sample of copper(II) oxide, CuO, needed to exactly neutralise 100 cm of 2 mol dm- nitric acid, HNO, [Relative atomic mass: 1,1; N, 14; 0,16; Cu,64] A 4g
B 8 g
C 10 g
D 16 g​

its option B

8 gram

just you divide mole mass / total number of of atom present in cuo

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
