There are 21 girls at the party.
Collect the molar masses of each element contained in LiOH.
- Lithium (Li) has a molar mass of 6.941 g/mol
- Oxygen (O) has a mass of 15.999 g/mol
- Hydrogen (H) has a mass of 1.008 g/mol
Together, LiOH has a molar mass of 23.948 g/mol.
Convert the given amount of LiOH from g to mol:
(67.03 g) * (1/23.948 mol/g) = 2.799 mol
C=2πR
C equals the <span>circumference of the circle, while π is 3.14 and R is the radius. them multiply that by 2

I got 13 but you didn’t put any answer choices
Hey how was ur day i hope u find this out
