Elden [556K]

Answer:

2M

M=mol/L

1. Find moles of CoCl2

mass of substance/molar mass = 130/129.833 = 1.001 mol

3. Substitute in molarity equation

M=(1.001/0.5)

M= around 2M

padilas [110]

Answer:

I believe that it is the 2nd option.

Explanation:

My reasonings are because C4H10O has 7 isomers. In which 4 are alcohol and the other 3 are ether.

The first option is ethers, specifically ethoxyethane.

The third option is ethers, specifically 1-methoxypropane.

The fourth option is an alcohol, specifically 1- butanol.

Therefore, leads us to the 2nd option that it is NOT an isomer of C4H10O
