Fuse should only affect voltage
Answer:
18.1 g
Explanation:
You know that the atomic weight of phosphorus is equal to
30.794 u
, where
u
represent the unified atomic mass unit.
The unified atomic mass unit is equivalent to
1 g/mol
, but let's take the long road and prove that identity.
Now, the unified atomic mass unit is defined as
1
12
th
of the mass of a single unbound carbon-12 atom in its ground state and is equivalent to
1 u
=
1.660539

This means that the mass of one phosphorus atom will be

You know that one mole of any element contains exactly
6.022
⋅

23
atoms of that element - this is known as Avogadro's number.
Well, if you know the mass of one phosphorus atom, you can use Avogadro's nubmer to determine what the mass of one mole of phosphorus atoms

Finally, if one mole of phosphorus atoms has a mass of
30.974 g
, then
0.585
moles will have a mass of
0.585

Answer:
After every 6 months opened containers of peroxide formers will be tested.
Explanation:
Opened containers from which peroxide formation take place will be tested after every 6 months for safe storage. And for unopened container the test will be conducted for peroxide formation is after 12 months from manufacturing expiry date or from receiving date.
