Someone please help I'm failing chemistry. The weight of a Mars bar has recently dropped from 58 grams to 51 grams. Mars says it's to encourage people to eat more healthily and keep the number of calories (the energy contained) in a standard bar, to fewer than 250. The planet Mars would have a mass how many times greater than a mole of Mars bars? Assume the mass of the Mars is 6.39 × 10^23 kilograms.

If soap hits the floor, is the soap dirty or the floor

Select the correct answer. given: 2libr + ba → babr2 + 2li in this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced? a. 1.18 mol b. 2.37 mol c. 4.73 mol d. 16.4 mol e. 32.9 mol

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
