Convert the following moles to grams :) 1. 2.4 moles sulfur
2. 1.5 moles BeI2
3. 7.5 moles C6H12O6

1. 76.8 g

2. 394.23 g

1351.1691 g

Explanation:

Use relative formula masses to work out the number of grams in a single mole and multiply with number of moles to work out the answer

Explanation:

sky is high and I am good.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
