(ii) Have you utilized the proper level of high numbers? thickness (1.03 ) possess step three significant numbers volume (1) enjoys step one significant contour When multiplying or separating, what number of extreme rates from the outcome is a similar because the minimum quantity of tall figures in the terms used, therefore we are justified in making use mexican chat of step 1 tall profile. The respond to (ten30) has 4 significant data! Due to the fact we have been simply justified in making use of step one high shape, we are able to provide the address as the 1000 grams, although best solution should be to have fun with scientific notation and you may write 1 ? ten 3 grams

(iii) Is the respond to plausible? Create a beneficial “rough” calculation: density ≈ step one grams mL -step one 1 mL of milk keeps scores of regarding the step 1 g step 1 L (a lot of mL) from milk possess scores of regarding the one thousand ? 1 = 1000 grams Because harsh formula is almost this new very carefully calculated worth to have size we have been relatively confident that the respond to is right.

Concern 5. On twenty-five°C and you may step one automatic teller machine stress, diamond have a thickness off 3.5 grams cm -step 3 . Determine the quantity in the cm step 3 regarding 0.50 grams out-of diamond from the 25°C and you may step one atm pressure.

step three.5 grams cm -step three ? V (cm step 3 ) = V(cm 3 ) ? 0.fifty g ? V (cm 3 ) step three.5 g cm -step 3 ? V (cm step 3 ) = 0.50 g
