Calculate the total mass of these letters in grams (mxe=131.29amu)

The total mass of 131.29 amu

= 2,196.10⁻²² grams

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons move around the nucleus.

The mass number is not the same as the atomic mass. The mass number is the number of protons and neutrons in one atom. While the atomic mass is a number that expresses the mass of one atom.

Atomic mass is expressed in special units, namely atomic mass units because the atomic mass is very small if expressed in units of grams or milligrams

This atomic unit uses the standard atomic mass, that is, the C-12 isotope

1 C-12 atom = 12 atomic mass units

1 atomic mass unit = 1/12 x mass 1 atom C-12

The mass of 1 proton is equal to the mass of 1 neutron, equal to 1 atomic mass unit and electrons have a smaller mass than both.

electron mass = 9.11.10⁻²⁸ g

proton mass = 1.6726.10⁻²⁴ g

neutron mass = 1,675.10⁻²⁴ g

The proton mass is considered to be equal to 1 atomic mass unit and a neutron which has a slightly larger mass is also considered to be equal to 1 atomic mass unit

1 unit of atomic mass (amu) = 1.6726.10⁻²⁴ g

So if there are 131.29 amu, you can convert them into

= 131.29 x 1.6726.10⁻²⁴ g

= 219,595.10⁻²⁴

= 2,196.10⁻²² grams

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
