Question

Hi :) It's a significant figures question - I was wondering if you count 12.4kg as 3 significant figures or not. The key answers (written in the photo) for the question didn't seem like they counted 12.4kg as sig figs... or (1) did and (2) didn't, in order to match the sig fig for the money value of $1255 (4 significant figures...)...?

    On the planet Xgnu, the most common units of length are the blim (for long distances) and the kryll (for shorter distances). Because the Xgnuese have 14 fingers, perhaps it is not surprising that 1400 kryll = 1 blim. Two cities on Xgnu are 36.2 bum apart. What is this distance in kryll? The average Xgnuese is 170 kryll tall. What is this height in bums? This hook is presently being used at Xgnu University. The area of the cover of this book is 72.5 square krylls. What is its area in square bums?
    When elemental iron corrodes it combines with oxygen in the air to ultimately form red brown iron(III) oxide which we call rust. (a) If a shiny iron nail with an initial mass of 23.2 g is weighed after being coated in a layer of rust, would you expect the mass to have increased, decreased, or remained the same? Explain. (b) If the mass of the iron nail increases to 24.1 g, what mass of oxygen combined with the iron?

    Although the preferred SI unit of area is the square meter, land is often measured in the metric system in hectares (ha). One hectare is equal to 10,000 m2. In the English system, land is often measured in acres (1 acre = 160 rod2). Use the exact conversions and those given in Exercise 47 to calculate the following. a. 1 ha = __________ km2 b. The area of a 5.5-acre plot of land in hectares, square meters, and square kilometers c. A lot with dimensions 120 ft by 75 ft is to be sold for 6500. What is the price per acre?
