In these revision exercises\u00a0you are asked to use the relationship between number of moles, gram formula mass and the mass of a substance to work out the answer. \u00a0You should be familiar with the triangle formula and how to manipulate it. \u00a0\r\nAll answers have been calculated based on the RAM values detailed in the SQA National 5 databook, published in 2021.<\/pre>\n<\/td>\n<\/tr>\n
