Answer:
0.1388 g
Explanation:
The mass of 
obtained on precipitation = 236 mg
1 mg = 0.001 g
Thus, Mass of = 0.236 g
Molar mass of = 233.43 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 0.001011 moles
According to the reaction,
Thus, moles of barium = 0.001011 moles
Molar mass of barium = 137.327 g/mol
Thus, Mass = Moles * Molar mass = 0.001011*137.327 g = 0.1388 g
Answer:
2. A resistor
3. Transistor
Sorry about before, go the answers now!
I believe the answer is 47.25g
let me know if you need the workings i'll try and put it up
Metals usually melt when forming iron
Answer:
Mass is the same but it weights 64 Newtons
Explanation:
First of Mass is the same in any sort of gravity. Now let's calculate weight
W = MG
where W = Weight
M = Mass
G = Gravity
W = (40kg)(1.6)
W = 64
Sorry for the spelling mistakes, hope this helps
