Which has more atoms 1.1 g of hydrogen atoms or 14.7g of chromium atoms?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr

The mass of an atom usually expressed in atomic mass units is its?
Atomic mass.
What is the atomic mass of silver?
The atomic mass of silver is approximately 107.87 atomic mass units.
What is the atomic mass of aluminum?
The atomic mass of aluminum is approximately 26.98 atomic mass units.
Which element is a transition element with a mass of 52?
Chromium (Cr) is a transition element with a mass of 52. Its atomic number is 24.
How many neutrons are there in Cr-54?
In Cr-54 (Chromium-54), the number 54 represents the atomic mass, which includes the total number of protons and neutrons in the nucleus. Since Chromium (Cr) has an atomic number of 24 (number of protons), you can subtract the atomic number from the atomic mass to find the number of neutrons. Therefore, there are 30 neutrons in Cr-54 (54 - 24 = 30).
How many grams are in 11.9 grams of chromium?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr
How many moles are in 11.9 moles of chromium?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr
What is the mass of one mole of chromium?
Three chromium bromides are known: CrBr2, CrBr3, CrBr4. * CrBr2: 247, 5985 mg of Cr per 1 g of bromide * CrBr3: 179,9145 mg of Cr per 1 g of bromide * CrBr4: 141,1209 mg of Cr per 1 g of bromide
How many protons electrons and neutrons in chromium?
Chromium has 24 protons, 24 electrons, and usually 28 neutrons (as it has an atomic mass of around 52 atomic mass units).
What is the element with a mass number 52?
The element with a mass number of 52 could be tellurium (Te) or antimony (Sb). Both of these elements have isotopes with a mass number of 52.
Which has more atoms 1.1 g of hydrogen atoms or 14.7g of chromium atoms?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr
What atomic number is chrominum?
The atomic Number for chromium is 24 and the atomic mass for chromium is 51.996 when we round it it's about 52 =================== Chromium has 5 isotopes with mass numbers ranging in sequence from 50 to 54.
What is formula mass of potassium diaqua dioxalato chromate?
The formula mass of potassium diaqua dioxalato chromate is calculated by adding the atomic masses of each element present in the compound. The formula for this compound is K[Cr(C2O4)2(H2O)2]. By summing the atomic masses of potassium (K), chromium (Cr), carbon (C), oxygen (O), and hydrogen (H) in the compound, you can determine the formula mass.
What is the atomis number of Cr?
The atomic number of Cr, which stands for chromium, is 24.
How many moles are present in260g of chromium?
To find the number of moles in 260g of chromium, you need to divide the given mass by the molar mass of chromium. The molar mass of chromium is approximately 51.996 g/mol. Dividing 260g by the molar mass gives you about 5 moles of chromium.
