Question

How many moles are there in 184 gram of sodium?
Valid answer accepted​

Answer 1

Explanation:

given mass of Na = 184 g

molar mass of Na = 21 g

no. of moles = given mass / molar mass

no. of moles = 21/184

no. of moles = 0.130

Answer 2

${\huge{\fcolorbox{blue}{purple}{No of moles are 8}}}$

No. of moles = n

GIVEN MASS = m

MOLAR MASS = M

GIVEN:-

Given mass = m = 184 gram

WE KNOW THAT

MOLAR MASS of sodium = 23 gram

Apply the formula ⬇️

$\bf number \: of \: moles \: = \frac{given \: mass}{molar \: mass} \\ \\ n = \frac{m}{M} \\ \\ = \frac{184}{23} \\ \\ = \frac{8}{1} \\ \\ = 8 Answer$
