How many moles are in 240g of caco3?

Using the periodic table, find the molar mass of each compound in CaCO3

CA = 40

C = 12

O = 16

Molecular Mass = 40 + 12 + (16 x3) = 100 grams.

Number of moles = given mass / molecular mass

Number of moles = 240 g / 100g = 2.4 moles

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
