Answer:
1.85g per cubic centimeter (g/cm3
Explanation:
because density=mass/volume, so it will be 50g divide by 27ml =. 1.85g/cm3
<u>Answer:</u> Silver has 47 electrons, 47 protons and 43 neutrons. Barium has 56 electrons, 56 protons and 76 neutrons.
<u>Explanation:</u>
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Atomic number = 47
Mass number = 90
Atomic number = Number of protons = Number of electrons = 47
Number of neutrons = Mass number - Atomic number = 90 - 47 = 43
Hence, silver has 47 electrons, 47 protons and 43 neutrons.
Atomic number = 56
Mass number = 132
Atomic number = Number of protons = Number of electrons = 56
Number of neutrons = Mass number - Atomic number = 132 - 56 = 76
Hence, barium has 56 electrons, 56 protons and 76 neutrons.
Answer:
You'll experience a grater deviation
Explanation:
<em>You'll experience a greater deviation in your measurements, meaning your measures will have a bigger difference between them, and the greater these deviations the less accurate will be the measuring.</em> This happens mainly because you're not replicating the measurement with the exact same conditions, in one of them you'll have an extra mass from the water.

Answer: 26.54 grams
Explanation:
To calculate the moles :
is the limiting reagent as it limits the formation of product and 
is the excess reagent
According to stoichiometry :
As 1 moles of give = 3 moles of 
Thus 0.369 moles of 
give =
of
Mass of 
Thus 26.54 g of will be produced from the given mass.
