Answer 1

Answer:

95u

Explanation:

Weight of Mg=24u

Weight of Cl=35.5u

Weight of MgCl2=Weight of Mg+2(Weight of Cl)

=24u+2(35.5u)

=24u+71u

=95u

Answer 2

Answer:

95 g

Explanation:

WE HAVE TO FIND THE MOLECULAR MASS OFMgcl2

WEIGHT OF mg=24

WEIGHT OF cl=35.5

so molecular mass of mgcl2

WEIGHT OF MGCL2=MASS OF MAGNESIUM+2(MASS OF CHLORINE)

=24+35.5*2

24+71

=95 g
