Answer 1

Answer:

given mass/molecular weight

Explanation:

hope this helps you

Answer 2

Answer:

first of all be my friend

your answer is

Explanation:

"M"_r " Na"_2"SO"_4"##=(2xx"23 u Na")+(1xx"32 u S")+(4xx"16 u O")="142 u Na"_2"SO"_4#

When working with moles, the relative atomic and formula masses are numerically equal the molar mass. Molar mass is the mass in grams of one mole of a substance. So the mass of one mole of sodium, #"23 u"#, would become #"23 g/mol sodium"#, and the mass of one mole of sodium sulfate, #"142 u"#, would be #"142 g/mol"#.
