d1 = 15 miles
t1 = 1 hour
d2 = 25 miles
t2 = 2 hours
d = 15 + 25 = 40 miles
t = 1 + 2 = 3 hours
Convert 477°C to degrees Fahrenheit.

The atomic mass of element B is 106.1 amu.
Given:
- The atomic mass of element A is 35.45 amu.
- A +B → AB
- 28.54 g sample of A combines with 85.42 g of another element B
To find:
The atomic mass of element B.
Solution:
The mass of element A = 28.54 g
The atomic mass of element A = 35.45 amu = 35.45 g/mol
Moles of element A :
=
A +B → AB
According to reaction, one mole of A combines with 1 mole of B , then 0.8051 moles of A will combine with:
Moles of B element = 0.8051 mol
Mass of element B used = 85.42 g
The atomic mass of element B =M
The atomic mass of element B is 106.1 amu.

Since we have the mass of the iron ingot we can get its volume by dividing the mass (4.578) by the density of iron (7874 kgm^-3) and we get that the volume is 5.8140716x10^-4 m^3. now we convert the volume from m^3 to cm^3(1m^3=1000000cm^3) and so by multiplying 5.8140716x10^-4 by <span>1000000 we get:581.4cm^3 (1 decimal place).
the volume for any cuboid is V=l x w x s we have the volume, the length and the width, so we plug in the values and solve for s

the answer is rounded to three significant figures
