Atomic mass of Sulfur = 32g

32g of Sulfur is one mole.

1g of Sulfur is $\frac{1}{32} moles$

96.21g of Sulfur is $\frac{96.21}{32} moles= 3moles(appx)$

$\boxed {\boxed {\sf 3 \ moles \ sulfur}}$

Explanation:

To convert from grams to moles, the molar mass is used. This value is the number of grams in 1 mole of a substance and it can be found on the Periodic Table. Look for Sulfur or S.

Sulfur: 32.07 g/mol

We use this as a ratio.

$\frac {32.07 \ g \ S}{1 \ mo;\l\ S }$

Multiply by the given number of grams.

$96.21 \ g \ S*\frac {32.07 \ g \ S}{1 \ mo\l\ S }$

Flip the fraction so the grams of sulfur cancel out.

$96.21 \ g \ S*\frac {1 \ mol \ S}{32.07 \ g \ S }$

$96.21*\frac {1 \ mol \ S}{32.07 }$

$\frac {96.21 \ mol \ S}{32.07 }= 3 \ mol \ S$

96.21 grams of sulfur is equal to 3 moles of sulfur.

Chemistry

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
