Find the number of moles in 3.70x10^-1 g of boron

Number of mole = 0.0342 mole of Boron

Explanation:

One mole of a substance is equal to 6.022 * 10^23 units of that substance.

According to the definition in chemistry, mole is defined as the mass of substance containing the same number of fundamental units.

To calculate the number of mole, we will use the formula

n = m/Mm

n = number of mole

m = number of mass

Mm = number of molar mass

Molar mass of boron = 10.811g/mol

Mass of boron = 3.70 * 10^-1g

Using the formula

n = m/Mm

n = 3.70 * 10^-1 / 10.811g/mol

n = 0.0342 mole

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
