A bottle containing 225 g of cleaning solution is used to clean hospital equipment. It's specific gravity is 0.830, what is the
Hatshy [7]

<u>Answer:</u> The volume of solution that was used is 271.08 mL

<u>Explanation:</u>

The relationship between specific gravity and density of a substance is given as:

\text{Specific gravity}=\frac{\text{Density of a substance}}{\text{Density of water}}

We are given:

Specific gravity of water = 0.830

Density of water = 1.00 g/mL

Putting values in above equation we get:

0.830=\frac{\text{Density of solution}}{1.00g/mL}\\\\\text{Density of solution}=(0.830\times 1.00g/mL)=0.830g/mL

To calculate the volume of solution, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Density of solution = 0.830 g/mL

Mass of solution = 225 g

Putting values in above equation, we get:

0.830g/mL=\frac{225g}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{225g}{0.830g/mL}=271.08mL

Hence, the volume of solution that was used is 271.08 mL

Si escuchas a alguien decir que la corriente eléctrica en un sircuito sale por el polo negativo de la pila y entra por el polo p
Mrac [35]

Answer:

It refers to the conventional sense of the elastic current

Explanation:

It is the traditional or the conventional sense of the elastic current as in the earlier days the experimenters and the scientist thought that the current moves out of the positive terminal or pole of the battery and enters through the negative pole or terminal of the battery.

It is because of the direction of the current flow as thought in early days, the sentence refers to the conventional sense.
