O-19 has a mass defect; O-18 does not have a mass defect.
O-19 has a nuclear binding energy; O-18 does not have a nuclear binding energy.
O-19 has more neutrons than protons; O-18 has equal numbers of neutrons and protons.

What is i fracture in the crust called when land move up, down or sideways

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?

What substance has a mass of 9.5g and volume of 2.1cm^3
