Convert heat to moles
WebUsing the periodic table we find that the mass of one mole is 12×12 + 22×1 + 11×16 = 342 grams. 1 cube of sugar is 4 grams, which is 4/342 = 0.01 moles. 1 cup is 237 milliliters, so 1 cube of sugar mixed with one cup of tea makes 0.01 moles / 237 milliliters × 1000 (to convert to liters) = 0.049 moles/liter. WebMar 12, 2024 · Consider the simple chemical equation: 2H2 + O2 → 2H2O The convention for writing balanced chemical equations is to use the lowest whole-number ratio for the coefficients. However, the equation is balanced as long as the coefficients are in a 2:1:2 ratio. For example, this equation is also balanced if we write it as 4H2 + 2O2 → 4H2O
