1. what mass of solid cocl2 would you need, to prepare 250 ml of 0.150 m solution of cocl2 from solid cocl2 and distilled water? show your calculations.

Respuesta :

The quantity of matter in an item is its mass. Scientists frequently use balances to quantify mass. Using an electronic balance or a beam balance, one may directly determine the mass of solids.

What is meant  by mass of solid?

The quantity of matter in an item is its mass. Scientists frequently use balances to quantify mass. Using an electronic balance or a beam balance, one may directly determine the mass of solids. A liquid's mass can be calculated by measuring its volume and using the density table to determine the liquid's density.

The kilograms is the SI unit of mass (Kg). To get an object's mass, divide its weight by the acceleration of gravity. The weight units must be changed to Newtons. For instance, 1 kg equals 9.807 N. If you want to know an object's mass on Earth, divide its weight in Newtons by the Earth's gravitational acceleration, which is 9.8 meters per second2.

Here, solute is solid cocl2 and our solvent is distilled water.

The volume of solute is generally ignored, so we would dissolve,

[tex]$250 \mathrm{~mL} \cdot \frac{\mathrm{L}}{10^3 \mathrm{~mL}} \cdot 0.150 \mathrm{M} \cdot \frac{129.9 \mathrm{~g}}{\mathrm{~mol}} \approx 5.68 \mathrm{~g}$[/tex]
