Answer:
7.99 × 10⁸ atoms
Explanation:
The diameter of Molybdenum atom is 418pm = 0.000000000418m
therefore to determine number of Mo Atoms that'll be required =
0.334 ÷ 0.000000000418 = 7.99 × 10⁸ atoms
Mass of one Mo atom = 1.59×10⁻²² g
Mass of 7.99 × 10⁸ atoms that'll be required = 1.59×10⁻²² × 7.99 × 10⁸ =
12.7041 × 10⁻¹³g.
Answer:
pressure and temperature (assuming volume is constant)
Explanation:
Answer:
1.56 J
Explanation:
The potential energy only depends on the vertical height from the ground level.
We consider the ground level to have zero P.E.
So when it is 2 m above the ground level,
P.E. = mgh
= 0.078×10×2
= 1.56 J
The following are heterogeneous mixture: MILK THAT IS SOLD AT THE STORE, A CAKE MIX AND MIXED NUT.An heterogeneous mixture is one which contained many parts which can be separated out.A smoothie is an homogeneous mixture because the juice of different fruits that are use can not be separated out.
