How many atoms present in 3MgO?
There are a total of 6 atoms present in 3MgO. This is because each formula unit of MgO consists of one magnesium atom and one oxygen atom, so for 3MgO, you would have 3 magnesium atoms and 3 oxygen atoms, totaling 6 atoms overall.
What is the molar mass of potassium bromide?
Potassium bromide is KBr, so by adding together their molar masses, we get 39+80=119gmol-1
Which gas is heaviest nitrogen hydrogen or oxygen?
Nitrogen is heavier than hydrogen but lighter than oxygen. In terms of molecular weight, nitrogen has a molar mass of about 28 g/mol, oxygen has a molar mass of about 32 g/mol, and hydrogen has a molar mass of about 2 g/mol.
The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
How do you determine the molar mass of isobutyl alcohol?
The boiling point of water is only 100 C, so water can not be used to heat the flask containing Isobutyl. Heat the flask containing the Isobutyl directly or heat it in a substance that has a boiling point above 108 C
State one way in which molecues of hydregen and molecues of oxygen different?
The molar mas of H2 is 16; the molar mass of O2 is 32.
How many atoms present in 3MgO?
There are a total of 6 atoms present in 3MgO. This is because each formula unit of MgO consists of one magnesium atom and one oxygen atom, so for 3MgO, you would have 3 magnesium atoms and 3 oxygen atoms, totaling 6 atoms overall.
B2O3 plus Mg plus heat equals 2B plus MgO?
3Mgo+2B
What does the chemical equation MgI AlO equal?
If it's a double replacement reaction, then 3MgI2 + Al2O3 --> 3MgO + 2AlI3
What is the molar mass of potassium bromide?
Potassium bromide is KBr, so by adding together their molar masses, we get 39+80=119gmol-1
What is the molar mass for silver nitrate?
CaCl2 = MM(Ca) + 2*MM(Cl) = 40 + 35.5 * 2 =111
When was Mas Mucho Mas created?
Mas Mucho Mas was created in 1980.
Mas y mas?
mas y mas means more and more in spanish
When was Mengejar Mas-Mas created?
Mengejar Mas-Mas was created on 2007-05-24.
What is the mass in grams of 2.50 X 10-2 of CdS?
To calculate the mass of CdS, we need to have the molar mass of CdS. Cadmium (Cd) has a molar mass of approximately 112.41 g/mol, and sulfur (S) has a molar mass of approximately 32.07 g/mol. Adding these together, we get a molar mass of approximately 144.48 g/mol for CdS. To find the mass of 2.50 x 10^-2 mol of CdS, we would multiply the number of moles by the molar mass: (2.50 x 10^-2 mol) x (144.48 g/mol) = 3.61 g of CdS.
What does viva mas mean?
"Viva mas" isSpanishfor "live mas".
Which gas is heaviest nitrogen hydrogen or oxygen?
