How to find moles?

You have three steps to convert mole values to grams.

1. Calculate how many moles are mentioned in the question.
2. Find the molar mass of the substance.
3. Multiply both the values.

If you take 6.022 x 10 ^ 23 atoms of any element then you’ll have the same number of grams of that element as the atomic weight of that element. This number (6.022 x 10 ^ 23) is called Avogadro’s constant and can be used to calculate the weight of any substance in grams given the number of atoms (or molecules).

Calculating Molar Mass For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms. The characteristic molar mass of an element is simply the atomic mass in g/mol.

three steps

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.

A gram is about:

• a quarter of a teaspoon of sugar.
• a cubic centimeter of water.
• a paperclip.
• a pen cap.
• a thumbtack.
• a pinch of salt.
• a piece of gum.
• the weight of any US bill.

How many gram/kilogram in 1 percent? The answer is 10.

To determine the percentage, we have to divide the value by the total value and then multiply the resultant to 100. Percentage formula = (Value/Total value)×100. Example: 2/5 × 100 = 0.4 × 100 = 40 per cent.

How to calculate percentage

1. Determine the whole or total amount of what you want to find a percentage for.
2. Divide the number that you wish to determine the percentage for.
3. Multiply the value from step two by 100.

The basic way to calculate a discount is to multiply the original price by the decimal form of the given percentage rate. To calculate the sale price of any item, we need to subtract the discount from the original price.

Thus 30% of 80 is (30/100) x 80 = 24.

Working out 25% of 80 If you are using a calculator, simply enter 25÷100×80 which will give you 20 as the answer.

Working out 35% of 80 If you are using a calculator, simply enter 35÷100×80 which will give you 28 as the answer.
