Answer:966.45ml
Explanation:
Using Charles law.. V1/T1=V2/T2
V1=535ml
T1=-25+273
=248k
T2= 175+273=448k
V2=?
V2= V1*T2/T1
V2=535*448/248
V2=239680/248
V2=966.45ml

Answer:</h2>
% Composition of elements:
- Magnesium = 75%
- Oxygen = 25%
Atomic mass of given elements:
- Magnesium = 24 g
- Oxygen = 16 g
Now, divide % composition by Atomic mass:
Simplest Ratio:
Empirical Formula:
Density:
The density of a substance is equal to the ratio of its mass and volume. In general we can say the density of a substance is mass per unit volume.
Density = mass in g / volume in cubic cm or ml
Given that
Density = 8.92 g/ ml
Mass = 40.0 g
Therefore,
Volume = mass/ density
= 40.0 g/ 8.92 g/ ml
= 4.48 ml
Thus the correct answer is 4.48 ml
Answer:
Nickel is the answer
Explanation:
Lol that's easy the atomic number is the same number as the number of electrons.
