3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
There are 1000 milligrams in one gram. Therefore, 345 milligrams is equal to 345/1000 = 0.345 grams.
The volume of a gas can be calculated using the ideal gas law equation: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. Rearranging the equation to solve for V gives V = (nRT)/P. Plugging in the values n = 0.24 mol, R = 0.0821 L.atm/mol.K, T = 345 K, and P = 0.75 ATM, we get V = (0.24 mol * 0.0821 L.atm/mol.K * 345 K) / 0.75 ATM ≈ 6.43 L.
1 mol of an element is equal to it's atomic weight, but with grams instead of amu (or daltons) as the unit. For example, with copper (Cu), 63.5 amu is its rough atomic weight, which means it weighs roughly 63.5g per mol. Then we just need to divide through. 63.5 x 0.345 = 21.9g
To calculate the mass of four moles of methane (CH4), we first need to determine the molar mass of methane. The molar mass of CH4 is the sum of the atomic masses of carbon (12.01 g/mol) and hydrogen (1.008 g/mol) multiplied by the number of atoms in the compound. Therefore, the molar mass of CH4 is 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol. To find the mass of four moles of methane, we multiply the molar mass by the number of moles: 16.04 g/mol x 4 mol = 64.16 grams. Therefore, four moles of methane would have a mass of 64.16 grams.
melting point of approximately 354°C 669.2°F
There are 1000 milligrams in one gram. Therefore, 345 milligrams is equal to 345/1000 = 0.345 grams.
345 grams of water is 1.521 cups345 grams of water is 1.521 cups
That is approximately 345 grams
A cup of frozen cranberries weighs 50 grams, so there are almost 7 cups of frozen cranberries in 345 grams.

There are 345 ones in 345.
first you must have a mass in mind. eg 345 grams of Carbon divided the mass by the molar weight of the particular substance. In the case of Carbon 12 grams/mole 345 grams/12 grams/mole = 28.75 moles
345 g = 0.345 kg345 g = 0.345 kg345 g = 0.345 kg345 g = 0.345 kg345 g = 0.345 kg345 g = 0.345 kgRemember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). These are the denominations you need to list when converting metric units. Kilograms are three places to the left of grams. So you have to move the decimal place three times to the left (same as dividing by 1000). You will get 345 g = .345 kg.
