To find the mass of 3.5 x 10^22 molecules of CO2, we need to multiply the number of molecules by the molar mass of CO2. The molar mass of CO2 is approximately 44 grams per mole. So, 3.5 x 10^22 molecules of CO2 would have a mass of approximately 1.54 x 10^25 grams.

What is the mass number of cl35?
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
What mass of NH3 can be made from 35.0 grams of N2?
The answer is 2,107749515.1025 molecules.
If the mass of water is 4.5 times greater than the mass of helium how does the mass of a water molecule compare with the mass of a helium atom?
The mass of the water molecules is greater than the mass of the helium atoms. It just so happens I had the same question in science, and that's what I put down. It might be wrong, it might not. But I'd be at least at like 65-35% chance it's right.
What is the full atomic symbols for isotope with mass number 35?
Chlorine is a non metal element. Mass number of it is 35.
What is the element if you have a mass of 35?
Chlorine
How many atoms in 35 mol carbon dioxide?
1 mol of any substance contains 6.02 x 1023 constituent particles. This is the avogadro constant. So in 35 moles of CO2, there would be 35 x 6.02 x 1023 molecules of CO2. In each CO2 there are three atoms (one carbon and two oxygen). Therefore the total number of atoms in 35mol of CO2 is 3 x 35 x 6.02 x 1023 = 6.32 x 1025
Why can chlorine molecules have three different values of mass number?
Chlorine atom has two isotopes - with Mass Number = 35 and 37. One Chlorine molecule can be any of three combinations - 35+35 = 70, 37+37=74 and 35+37 = 72.
What is cos (35)?
Normal CO2 in the blood is the same as Normal PH. Ph is 7.35-7.45 CO2 is 35-45
How many moles of C are in 90g of CO2?
Divide mass (g) by molar mass (g/mol) : 30 g C2H2 = 30/26 g 35 g H2O = 35/18 g
What elemsnt has the atomic mass of 35?
Chlorine is a meta element. Atomic mass of it is 35.
How many Cl2O molecules of different mass naturally exist?
You have to take into account the possibility of forming molecules from the natural isotopes of chlorine (Cl-35 and Cl-37) and those of oxygen (O-16, 17, 18).
What is the mass number of cl35?
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
What is true about an atom with a mass number of 35?
Chlorine is a non metal element. Mass number of it is 35.
Can I be rearrested on a section 35 if I leave in mass?
Yes, you could be rearrested on a section 35 if you leave in mass
What is normal CO level?
Normal CO2 in the blood is the same as Normal PH. Ph is 7.35-7.45 CO2 is 35-45
How many neutrons are in CI-35?
Answer: 20 You have to subtract the atomic mass from the protons. So it's 35-15=20 15 is the number of protons. 35 is the atomic mass.
What mass of NH3 can be made from 35.0 grams of N2?
The answer is 2,107749515.1025 molecules.
