What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%
If the half life of a radioactive substance is 10 hours how long will it take for 75 percent of it to decay multiple choice question is it 15 hours 10 hours 5 hours or 20 hours?
Its 5 hours. 50% of the substance is decayed at 10 hours (that is what half life means. It's full life is 20 hours). Multiple 75% times 20 hours to find that 75% is 15 hours. Subtracrt 15 hours from 20 hours to get the answer of 5 hours for the decay of 75% of the substance.
Using the Kw equation how is it possible to determine whether an aqueous solution is acidic basic or neutral?
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
Calculate the velocity of a neutron with a wavelength of 75 pm?
To calculate the velocity of a neutron with a given wavelength, you can use the de Broglie wavelength formula: λ = h / mv, where h is the Planck constant, m is the mass of the neutron, v is the velocity, and λ is the given wavelength. Solve for v to find the velocity of the neutron.
How many protons are in rhodium?
Rhenium has 75 protons, 75 electrons and 111 neutrons.The number of protons is equal to the number of electrons.Neutrons can be calculated by subtracting the number of protons from the atomic weight.In this case atomic number is 186 ==> the nr of neutrons = 186-75=111.

How many 12 x 12 inch tiles to cover 75 square foot?
75 tiles would do it (a 12*12 inch time = 1 square foot) but you need 10% over this for waste so you need to get 83 tiles.
What times point 75 equals 12?
x = 16 x * .75 = 12 12 / .75 = x
How do you do 75 times 20?
75*20 = 75*(2*10) = (75*2)*10 = 150*10 = 1500
What it greater 12 over 12 or 75?
(I guess what you are trying to ask is whether 12 / 12 is bigger or 12 / 75?) 12 / 12 is bigger. Think about it in terms of, let's say... cups. If you are looking at 12 / 12, all 12 cups out of 12 are filled up so the whole thing is full. Now, if you look at 12 / 75, there are tons of cups but only a few of them are filled up and most of them are empty.
What is 75 percent out of 10?
75% is equal to 3/4. So 75% of 10 = 3/4 of 10 = 7.5
