An atom has an atomic mass of 101g and has 57 neutrons what is the atomic number?
If an atom has an atomic mass of 101g and 57 neutrons, then:Atomic Mass = (number of protions) + (number of neutrons) 101 = (X) + (57) or.... (101) - (57) = x 101-57=44 the element that has 44 as its atomic number would be RutheniumAs we know mass of atom is primaril constituted by the neutrons and protons,while the mass of electron is neglegible.Taking mass of proton equal to mass of neutron and both having a unit mass.we can say that mass of an atom is equal to the number of protons and neutrons multiplied with the mass of i proton/neutron.we are given mass of lithium =7=>(no. of neutron + no. of protons)*(mass of 1 proton/neutron)=7=>no. of neutrons + no. of protons *(1)=7=>no. of neutrons=7-no. of protons=>no. of neutrons=7-3 (atomic no=no. of protons)=>no. of neutrons=4
Is 44 amu is equal to molecular mass?
No, 44 amu (atomic mass units) refers to the average mass of an atom of an element. Molecular mass, on the other hand, refers to the sum of the atomic masses of all the atoms in a molecule. So, they are not equal.
What is calciums average atomic mass?
The average atomic mass of calcium is approximately 40.08 atomic mass units (amu). This value accounts for the relative abundance of its stable isotopes, primarily calcium-40, calcium-42, calcium-43, calcium-44, and calcium-46. Because isotopes have slightly different masses, the average reflects the weighted contributions of each isotope based on their natural abundance.
How many grams of H is in 44 grams of C13 H18 O2?
Given C13H18O2 (which is ibuprofen, by the way) the molar mass is 206g/mol. (This figure is derived from adding the atomic masses of all the constituent atoms of that compound.) The percent composition by mass of the hydrogen in ibuprofen is 18/206=0.087, which is 8.7%. The given mass is 44g, so 8.7% of 44 = 3.83g hydrogen.
What elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.
Carbon dioxides atomic mass?
Carbon's atomic relative atomic mass is roughly 12 and oxygen's roughly 16. CO2 therefore is 12 + (16 * 2 ) = 44 units. So the relative _molecular_ (it can't be atomic as CO2 isn't an atom) mass of carbon dioxide is 44 units.
What is the mass of Co2 in atomic mass unit?
44 amu
What is the mass of CO2 in the atomic mass units?
44 amu
What is mass of CO2 in atomic mass units?
44 amu
What is the mass CO2 in atomic mass units?
44 amu
What is the mass of 2.00 moles of carbon dioxide CO2?
to work out the number of moles, you divide the mass by the relative atomic mass so 200 divided by 44 = 4.55 moles

How many protons does ruthenium have when the atomic number is 44 and the mass number is 101?
Ruthenium has 44 protons since the atomic number represents the number of protons in an atom. Since the mass number is 101, it implies the sum of protons and neutrons in the nucleus is 101, so the number of neutrons in this case would be 101 - 44 = 57.
What is calciums average atomic mass?

What element has a mass number of 44?
The closest to 44 is Scandium, which has 21 protons and 24 neutrons, giving it a mass of 44.95591 amu.
The number of neutrons in ruthenium?
