Question

240 grams of calcium and 240 grams of magnesium element have a mole ratio of 3:5

Answer 1

given mass= 240 g of calcium and 240 g of mg

gram atomic mass of Ca= 40 g and Mg= 24 g

mole= given mass/gram atomic mass

       = 240/40 g =6 mole of Ca

     = 240/24 g=10 mole of Mg

= ratio= 6:10= 3:5

hope it helps thank u  mark it as best

Answer 2

Answer:

3:5

Explanation:

Number of moles in 240g Ca metal =

40

240

=6

Number of moles in 240g of Mg metal =

24

240

=10

Ratio=6:10

Ratio=3:5
