Question: Hey peeps Idk what to do with a lab i have. The question is asking: Determine the moles /L and pH of the acid. What do i need to do to solve this problem. -do i need the molar mass? I have no clue what im doing lol. Best Answers: Chemistry What to do? Anita | 9 days ago
You've not given enuf information. duh. you don't need the molecular weight if you have an alternative way to calculate number of moles. PV=nRT, freezing point depression, beers law, the list goes on and on. Otherwise, yes you need the weight and the molar mass. for pH. duh. again not enuf info. pH in water? with no other ions present? strong acid or weak? if strong acid then M =>[H+] ->pH otheriwse you either need to calculate it or measure it.

Plug in the values you have 0.00307g of matter c = 3.0 x 10^8 so E= 0.003.07 x c^2 E= 2.763 x 10 ^14J = 2.763 x 10^8 MJ 2) 5.98 MJ = mc^2 5.98MJ / c^2 = m 5.89x 10^6 / 9 x 10 ^16 = 6.5 x 10 ^-11 grams Originally Answered: Can someone help me solve this chemistry problem on nuclear chemistry?
because of the certainty the mass sort of the two nuclei is an identical, the great sort of protons and neutrons is comparable. Carbon has 6 protons and 5 neutrons. Boron has 5 protons and six neutrons. this shows between the carbon’s protons has replace precise right into a neutron. The can value of a proton is +a million. The can value of a neutron is 0. +a million + x = 0, x = -a million The can value of the particle is -a million. A beta particle has a can value of -a million and an identical mass as an electron. Proton + ?- ? Neutron OR Proton + e- ? Neutron C + ?- ? B OR C + e- ? B Mass of proton = a million.67265 * 10^-27 kg Mass of neutron = a million.67495 * 10^-27 kg The mass of a neutron is larger desirable than the mass of proton, because of the certainty a neutron has beta particle indoors it! jointly as the particle we call an electron is indoors the nucleus, we call it a beta particle!
