How many moles are in 10 grams of CaCl2?

n = 0.0901 mole

Explanation:

n = m/Mm

n = number of mole

m = number of mass

Mm = number of molar mass

Given

CaCl2

m = 10grams

Mm of CaCl2

Ca = 40.078

Cl = 35.453

CaCl2 = 40.078 + 2(35.453)

There are two atoms of Cl

= 40.078 + 70.906

= 110.984

m = 10g

n = m/Mm

Insert the values

n = 10/110.984

n = 0.0901 mole

The number of mole is 0.0901mole

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
