Calculate the mass of 5.8 moles of nitric acid (HNO3). Explain the process or show your work by including all values used to determine the answer.

Mass = 365.45 g

Explanation:

Given data:

Mass of HNO₃ = ?

Number of moles of HNO₃ = 5.8 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of HNO₃ is 63.01 g/mol

By putting values in the formula,

Mass = 5.8 mol × 63.01 g/mol

Mass = 365.45 g

5.8 moles of HNO₃ have 365.45 gram mass.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

you need to have a picture of the atom that way we can answer it
