it allows the chemist to weigh quantities of two substances, say iron and sulphur, in order to obtain equal numbers of iron and sulphur atoms. a mole of a substance is known as a material mass containing the same number of basic units as atoms in exactly 12,000 g of 12c. q2 why is...
There are 237 grams in a cup of water. To get this value: Use the density formula: density = mass/volume Rearrange the formula as: mass = density × volume Substitute the values into the formula. We assume water has a density of 1 g/ml, and 1 cup is equal to 237 ml. This means...

The mass in a piece of iron is much larger than the same-sized wooden piece. We get the indication of the mass of a body by the weight which is actually the force with which the Earth is pulling it. In this lesson, we will learn about mass and weight in detail and learn other ...
