Answer:

Molar mass = 103.0 g/mol,

0.728 mol NaBr

Explanation:

Molar mass M(NaBr) = M(Na) + M(Br) = 23.0 + 80.0 = 103.0 g/mol

75.0 g NaBr * 1 mol NaBr/103.0 g NaBr=0.728 mol NaBr

Julli [10]

Well, first we must remember that

$pK_{a}+pK_{b}=14$

This is because

$K_{a}*K_{b}=10^{-14}$

$-log(K_{a}*K_{b})=-log(10^{-14})\\-logK_{a}+-logK_{b}=-log(10^{-14})\\pK_{a}+pK_{b}=14$

So then

$pK_{b}=14-pK_{a}=14-3.2=1.8$

1. EXPLAIN the steps required to find the molar mass of NH3 . Also,

Natasha_Volkova [10]

Answer: Molar mass of $NH_3$ is 17.03 g

Explanation:

Molar mass is defined as the mass in grams of 1 mole of a substance.

S.I Unit of Molar mass is gram per mole and it is represented as g/mol.

It is found by adding the atomic masses of all the elements present.

Atomic Mass of Nitrogen (N) = 14.007 g

Atomic Mass of Hydrogen (H) = 1.008 g

Molar mass of $NH_3$ = 1(14.007)+3(1.008) g = 17.03 g
