<span>A process or reaction which takes in heat from the surroundings is said to be </span><u>Endothermic.</u>
Answer:
Explanation:
We are given the compound: Cs₃PO₄
According to the formula, 1 mole of cesium phosphate contains 3 moles of cesium, 1 mole of phosphate, and 4 moles of oxygen.
Therefore, there are 3 moles of cesium for 1 mole of cesium phosphate.
We want to calculate the moles of cesium in 3 moles of cesium phosphate, so we multiply the ratio by 3.
3 moles of cesium phosphate contains <u>9 moles of cesium.</u>
