|---|---|---|
| 6 as density for J or K | B1 | |
| 13 as volume for K or \(78 \div\) their 6 as volume for K | B1ft | ft their 6 |
| g/cm\(^3\) as units for densities of J and K and cm\(^3\) as unit for volume of K | B1 | allow g cm\(^{-3}\) |
Additional guidance
| Mark table first | |
| Full marks are only awarded for a fully correct table with no errors or omissions | |
| 13 cm\(^3\) as a volume for K, 0.006 kg/cm\(^3\) for both densities | B1B1B1 |
| Condone g per cm\(^3\), gpcm\(^3\) or g per cubic centimetre as units for density |
