23 The mass of a silver coin is 48.3 g
The density of silver is 10.5 g/cm3
Work out the volume of the silver coin.
(2)
| Scheme | Marks |
|---|---|
| \(10.5 = \dfrac{48.3}{v}\) or \(10.5v = 48.3\) or \((v =)\;\dfrac{48.3}{10.5}\) | M1 |
| Correct answer scores full marks (unless from obvious incorrect working) Answer: 4.6 | A1 |
| (2) | |
| (2 marks) |
Notes
M1: oe for substituting 10.5 and 48.3 correctly into a correct formula for density; may use any letter for the volume
A1: allow \(\dfrac{23}{5}\) or \(4\dfrac{3}{5}\) oe
