Question

What is the molar mass of Mn(ClO3)2? Explain how you calculated this value. Please please help me!

Answer 1

use the periodic table and add the molecular masses of each element in the formula together in their respective ratios.

1 Mn + 2( 1Cl + 3 O) =

Answer 2

what does that mean I don't mean to be annoying I just don't get this

Answer 3

Do you have a periodic table?

It's asking you to add up their individual mass to find the total mass.

Answer 4

What are they? like what am I suppose to add? THANK YOU for helping me !

Answer 5

You're adding their molar masses/molecular weights (they have different names)

Answer 6

They're all on the periodic table, for example, chlorine's is 35.45 g/mol

Answer 7

what does mn mean?

Answer 8

Manganese

Answer 9

86. 93+ 35.45= 122.38

Answer 10

what do I do now?

Answer 11

You need to add Cl 2 times and oxygen 6 times, look at their coefficients

Answer 12

Mn = 55g/mole
Cl = 35.4g/mole x 2 --> 70.8
O = 16g/mole x 6 --> 96
Now just add it up!
55+96+70.8!
