<u>Answer:</u> The mass percent of silicon in the given compound is 15.9 %
<u>Explanation:</u>
We are given:
A chemical compound having chemical formula
To calculate the percent by mass of silicon in given compound, we use the equation:
Mass of silicon =
Mass of compound =
Putting values in above equation, we get:
Hence, the mass percent of silicon in the given compound is 15.9 %
Answer:
A. Protons and neutrons have similar mass
F. Electrons are smaller than a proton or a neutron
Considering the molar mass of
S = 32gmol¯¹
O = 16gmol¯¹
Therefore
SO3 = 32+(16×3)
= 32+ 48
= 80gmol¯1
1 mole of NaHCO3 = 84g
1 mole of NaHCO3--------------84g
x moles of NaHCO3----------0,50g
x = 0,00595 moles of NaHCO3
0,00595 moles of NaHCO3----------in--------250ml
x moles of NaHCO3-------------------in-----------1000ml
x = 0,0238 moles of NaHCO3
answer: the molar <span>concentration of NaHCO3 is 0,0238mol/l</span>
The charge alters that space, causing any other charged object that enters the space to be affected by this field. The strength of the electric field is dependent upon how charged the object creating the field is and upon the distance of separation from the charged object.
