Question
3.14 Calculate each of the following quantities:
(a) Mass in grams of mol of
(b) Moles of compounds in 15.8 kg of
(c) Number of N atoms in 92.6 mg of
Step-by-Step Solution
Verified Answer
- Mass in grams of mol is .
- Moles of compounds in 15.8 kg is .
- The number of O atoms in is .
1Step 1: Introduction to the Concept
The mass of a substance made up of an equal number of fundamental units is defined as a mole.
2Step 2: Determination of Mass in grams of 6 . 44 × 10 - 2 mol of MnSO 4
a)
Let’s compute for molar mass of
We multiply the supplied number of moles of by the mass in grams to get the mass in grams.
3Step 3: Determination of moles of compounds in 15.8 g of Fe ( ClO 4 ) 3
b)
The following is the molar mass of
The mass of is multiplied by the reciprocal of its molar mass. We multiply 1000 kg to it.
4Step 4: Determination of Number of N atoms in 92.6 mg of NH 4 NO 2
c)
The following is the molar mass of
We get when we convert the provided mass in milligrams to grams. The mass of is now multiplied by the reciprocal of its molar mass, the number of moles of N atoms per mole of and Avogadro's number.
