What mass of protons would be required to just neutralize the charge of 4.4 g of electrons?
To find the mass of protons needed to neutralize the charge of 4.4 g of electrons, we first calculate the number of electrons in that mass. The charge of one electron is approximately (1.6 \times 10^{-19}) coulombs, and the mass of one electron is about (9.11 \times 10^{-31}) kg. Thus, 4.4 g of electrons corresponds to approximately (4.84 \times 10^{22}) electrons, which would require an equal number of protons to neutralize the charge. Since the mass of a proton is about (1.67 \times 10^{-27}) kg, the mass of protons needed would be approximately (8.06 \times 10^{-5}) kg, or 0.0806 g.
Which one particle has a mass of approximately atomic mass unit and a unit positive charge?
none of the particles are 1g. (g stands for gram which is about the weight of a small paperclip.) however the proton has a positive charge.
How much charge is present on 500 mg of electrons?
To calculate the charge on 500 mg of electrons, we first convert the mass to grams: 500 mg = 0.5 g. The number of moles of electrons can be found using the molar mass of electrons, which is approximately 0.00054858 g/mol. Therefore, 0.5 g corresponds to about 910 moles of electrons. Since each electron has a charge of approximately -1.602 x 10^-19 coulombs, the total charge is about -1.46 x 10^21 coulombs.
How many g less then 4kg is the total mass of 10 parcels each having a mass 345 g?
The total mass of 10 parcels, each weighing 345 g, is 3,450 g (10 x 345 g). To find out how many grams less than 4 kg this total mass is, first convert 4 kg to grams: 4 kg = 4,000 g. Then, subtract the total mass of the parcels from 4,000 g: 4,000 g - 3,450 g = 550 g. Therefore, the total mass of the parcels is 550 g less than 4 kg.
How many formula units make up 21.8 g of magnesium chloride (MgCl2)?
To find the number of formula units in 21.8 g of magnesium chloride (MgCl₂), first calculate its molar mass. The molar mass of MgCl₂ is approximately 95.3 g/mol (24.3 g/mol for Mg and 35.5 g/mol for Cl, multiplied by 2). Next, divide the mass of MgCl₂ by its molar mass: 21.8 g ÷ 95.3 g/mol ≈ 0.229 moles. Finally, multiply the number of moles by Avogadro's number (6.022 × 10²³) to find the number of formula units: 0.229 moles × 6.022 × 10²³ ≈ 1.38 × 10²³ formula units.

What is the atomic mass for protons?
The mass of a proton is 1.67 x 10-24 g.
Using the mass of the proton 1.0073amu and assuming its diameter is 1.010-15 m calculate the density of a proton in gcm3?
To find the density of a proton, we first need to calculate its volume. Knowing that the diameter of the proton is 1.010-15m, we can determine its radius (0.505x10-15m). Using the volume formula for a sphere, V = 4/3 * π * r^3, we find the volume to be 4.22x10-45 m^3. Converting the mass of the proton to grams (1.6726219x10-24 g), the density is approximately 3.97x10^17 g/cm^3.
Distinguish between the subatomic particles in terms of relative charge and mass?
Protons have a positive charge and a mass of about 1 atomic mass unit (u). Neutrons have no charge (neutral) and a similar mass to protons. Electrons have a negative charge and a much smaller mass compared to protons and neutrons.
What is the charge of a neutron and a neutron together?
The charge on a neutron is zero. It has no electrical charge; it is a neutral particle.As the name suggests, the neutron is neutral, with neither positive nor negative charge.
What is approximately1.67 x 10-24 g?
The number itself is a physical constant representing the mass of a proton/neutron in grams assuming the "-24" is the power of 10.
What mass of protons would be required to just neutralize the charge of 1.0g of electrons?
1 proton would neutralize 1 electron. According to wikipedia, "An electron has a mass that is approximately 1/1836 that of the proton." so you'd need 1836/1 fold the mass of electrons, or in this case 1,836g of protons.

A student makes scale models of the subatomic particles. He uses an object with a mass of 1 g to represent an electron. Approximately what mass should the object have that he uses to represent the proton?
Approximately 1836 times greater, so the object representing a proton should have a mass of about 1836 g (1 g * 1836 = 1836 g).
What is 10 g?
10 g = 10 grams
