You are performing an experiment in your lab. to compare with other experiments you need your results to be in moles. during your final step you collect your product and weigh it. you have 600 grams of mg(h2po4)2 (magnesium dihydrogen phosphate). how should you enter your results?

To be able to compare the result with other experiments it has to be reported in moles.

number of moles = mass / molecular weight

number of moles of Mg(H₂PO₄)₂ = 600 / 218 = 2.75 moles

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
