How much does 1 ml of methanol weigh?
Methanol, CH4O, has a molar mass of 32g (12g+4.0g+16g)* *note this is only rounded to two sig figs, since the mass of elements are usually rounded to the tenths place. Next, simply use dimensional analysis: 1ml/22.4L X 32g. you should get the right answer by doing the steps shown above.
How do yu convert 12g into kg?
Move the decimal three place to the left. start at 12.0g ---> 1.2 -----> 0.12 -----> end with 0.012kg
A 12g rifle bullet is fired with a speed of 380 v into a ballistic pendulum with mass 6 kg suspended from a cord 70 cm long What is the vertical height through which the pendulum rises?
Wiki doesn't do your homework, so it is time to get busy. OH yeah that's what i said oh yeah u tokd him/her (whoever asked this question)
How do you convert 3 moles of NaC2H3O2 to grams. the numbers after the letters are suppose to be subscripts?
Use the molar masses for sodium (23g/mol) carbon (12g/mol), hydrogen (1g/mol) and oxygen (16g/mol). Add them together in the amounts indicated by the subscripts. Multiply the 3mol by this number and you have your mass in grams!(values are approximate, a good chemistry textbook will have more accurate values).
What is the total negative charge in coulombs of all the electrons in a small 1.00 g sphere of carbon?
1.00g of Carbon = 12g/mol 1.00g x 1mol/12g = .0833 mol/C .0833 mol of C x (6.02 x 10^23/1 mol of Carbon) x 6 electrons/1 C atom = 3.01 x 10^23 3.01 x 10^23 protons x -1.602 x 10^-19 (1 electron) = -48220.2 Coulombs OR -4.8 x 10^4
What is the approximate density of the cube if each side was 3cm and the mass is 12g?
Density = mas/volume = 12 g/27 cc = 0.44... recurring grams per cubic centimetre.
What is the density of an object with a mass of 12 grams and a volume of 3cm3?
Density = mass ÷ volume = 12g ÷ 3cm3 = 4 g/cm3
What is the density of an object with a volume of 8 cm3 and a mass of 12g?
Density = Mass/Volume = 12/8 = 1.5 grams per cm3
What is the density of a toy with a mass of 12g and a volume of 13ml?
Density = Mass/Volume = 12/13 g/ml = 0.923 g/ml approx.
How do you find the density of a cube that is 3Cm each side and weighs 12G?
Density = grams/cm^3 (cc) 3 cm^3 = 27 cm^3 Density = 12 grams/27 cm^3 = 0.4 grams/cm^3 ----------------------------
If the mass of a box is 12 grams its volume is 10 cm squared what is the density?
The density of the solid is about 0.86 g/cm3
What does one mole of carbon have a mass of?
12g
What is the realative atomic mass of Carbon?
12g
What is the mass carbon present in 44g of carbon dioxide?
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.
A rectangular solid is 3 cm long 2 cm wide 1 cm mass is 12g What is its density?
What you do find the volume by multiplying the height the width and the length So... 3x2x1=6 Then you divide the mass by the volume m/v= 12 / 6 So... The answer is 2cm3
A cubical piece of rubber 2cmx2cmx2cm is found to have a mass of 12g What would be the mass of a cubical piece of rubber of dimension 4cmx4cmx4cm?
96 g
How many millimoles are in 12g of sodium hydroxide?
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
