## How do you calculate mass to moles?

Crayfish require an aquatic habitat. You should have holding tanks and habitats prepared before receiving your shipment. **Use conditioned tap water, spring water, or well water**. The water should cover the back of the animal, and needs to be no more than 15 cm (6″) deep.

## How did you convert grams to moles?

**Divide the number of grams of the compound, NaOH, by the molecular weight** And as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

## What is mass mole conversion?

The simplest type of manipulation using molar mass as a conversion factor is a mole-mass conversion (or its reverse, a mass-mole conversion). In such a conversion, we **Use the molar mass of a substance as a conversion factor to convert mole units into mass units** (or, conversely, mass units into mole units).

## How many moles are in 15 grams of nacl?

## How do you convert 22 grams of co2 to moles?

So, 22 gm of CO2 = **4422 moles of CO2 = 0.5 moles of CO2**.

## How do you calculate the mass?

One way to calculate mass: **Mass = volume × density**. Weight is the measure of the gravitational force acting on a mass.

## How many grams are in moles?

The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = **1 g/mol**.
