What is the volume of 70.0 g of ether if density os 0.70 g/mL
sdas [7]
D = m / V

0.70 g/mL =  \frac{70.0g}{V}

V =  \frac{m}{D}

V =  \frac{70.0g}{0.70g/mL}

V = 100 mL

hope this helps!

Conversion of minus 1 coulomb meter in debye
Viktor [21]

Answer:

-1 Coulomb meter = -2.997 × 10²⁹ Debye

Explanation:

Given:

Coulomb meter = -1 CM

Find:

In debye

Computation:

We know that,

1 Coulomb meter = 299,792,458,178,090,000,000,000,000,000 Debye

So,

-1 Coulomb meter = -299,792,458,178,090,000,000,000,000,000 Debye

-1 Coulomb meter = -2.997 × 10²⁹ Debye
