How many molecules of H2(g) are there in a 21.25 gram sample?
To calculate the number of molecules, you first need to determine the number of moles of H2 in the 21.25 gram sample using the molar mass of H2 (2 grams/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How do you convert gram to mil gram?
Multiply by 1000
How do you convert a gram of salt into milligrams?
There are 1,000 milligrams in a gram.
Which has more molecules a gram of CO2 or a gram of H2?
A gram of CO2 has more molecules than a gram of H2 because CO2 has more atoms per molecule (three atoms in CO2 compared to two in H2). Thus, CO2 will have a higher total number of molecules per gram.
Why does it take 80 calories to convert 1 gram of water to 1 gram of steam?
Water molecules attract each other; energy is required to overcome that attraction. In other words, the change of phase implies a change in potential energy.
Which has more kinetic energy the molecules in a gram of ice or a gram of steam?
The molecules in a gram of steam have more kinetic energy than the molecules in a gram of ice. This is because steam has a higher temperature and its molecules are moving faster compared to the slower-moving molecules in ice.
How many naphthalene molecules does a naphthalene C10H8 mothball that has a mass of 1 gram contain?
To determine the number of naphthalene molecules in a 1-gram naphthalene mothball, you would first calculate the number of moles of naphthalene using its molar mass (C10H8) and then use Avogadro's number to convert moles to molecules. Given that naphthalene's molar mass is 128.17 g/mol, you would find that there are approximately 6.022 x 10^21 molecules in a 1-gram naphthalene mothball.
How many molecules in 12 gram in ice?
The number of molecules is 4,015.10e23.
How many molecules in 12 gram of ice?
The number of molecules is 4,015.10e23.
How many molecules are in 1 gram of carbon dioxcide?
There are approximately 1.13 x 10^22 molecules in 1 gram of carbon dioxide.
How do you convert 325 mg to 1 gram?
-- The only way to convert 325 mg to 1 gram is to find another 675 mg somewhere to add to it. 1,000 mg = 1 gram 325 mg = 0.325 gram
How do you convert gram in to a gallon?
You don't. A gram is a measure of weight, a gallon is a measure of volume.
