I'll give a lot of points if you can help: How many C atoms are present in a 7.37 ng sample of quinine, C20H24O2N2? Note: 1 ng is one nanogram. Enter your answer in exponential notation, e. g. 1.23e20 for 1.23x1020. Do not include any units or words as part of your answer. Give your answer accurate to three significant figures. Molar masses (in g mol−1): H, 1.008 C, 12.01 N, 14.01 O, 16.00

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

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?

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
