To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
Themolecular massor molecular weight is the total mass of a compound. It is equal to the sum of the individual atomic masses of each atom in the molecule. It's easy to find themolecular massof a compound with these steps: Determine themolecular formulaof the molecule. Use the periodic tabl...
It's either the easiest way to double or even triple your savings, or a sure-fire ticket to bankruptcy. Let's explain. First of all, compound interest is different from simple interest. Simple interest is a fixed rate over time, based on the initial amount you've invested. If you've ...
Compound interest is a great thing when you are earning it! Compound interest is when a bank pays interest on both the principal (the original amount of money)and the interest an account has already earned. To calculate compound interest use the formula below. In the formula, A represents ...
To calculate empirical formula of a compound, find the mass of each element present in the compound and convert it to moles, calculate the individual mole ratios and then write out the empirical formula. There are numerous ways in which information regarding the molecular structure and composition...
This calculation means that you need one mole of salt. Now, you need to use the molar mass of salt in order to calculate how much you need to weigh out. 1mol(58.44g1mol)=58.44g This calculation means that if you wanted to make a 1 liter solution of 1M NaCl, you would need to ...
How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that compound. The molar mass of elements tells you the molar mass of a compound, so ...
How to Calculate Compound Interest The compound interest formula[1]is as follows: Where: T= Total accrued, including interest PA= Principal amount roi= The annual rate of interest for the amount borrowed or deposited t= The number of times the interest compounds yearly ...
100 = 40 per cent how to calculate the percentage of a number? to calculate the percentage of a number, we need to use a different formula such as: p% of number = x where x is the required percentage. if we remove the % sign, then we need to express the above formulas as; p/...
To calculate density, you divide the mass by the volume: Density = Mass ÷ Volume Density is often written in mathematics as the symbol p or D. Mass can be written as m, and volume can be written as V. So if you want to be fancy, the formula looks like this: ...
