in 890,000,000 there are two significant figures.
A significant figure is a number that is not 0, except when 0 is between two non zero significant figures.
e.g. 800900000 has 4 significant figures (8009), 7.56 has 3 significant figures etc.

Ont thousand milliliters (ml) equals one liter (L).
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.

There are four sig figs in 67.05mL.
890 ml = 30.09 US fluid ounces.
Milliliters can be converted to liters by dividing the number of milliliters by 1,000. 890 milliliters is the same as 0.89 liters.
It would be 0.99996 g/ml and to 4 sig. figs. that would be1.000 g/ml
There are approximately 30 ounces in 890 milliliters.
the density of the unknown metal is 8900g/mL d=m/v d=178000g/20.0mL=8900g/mL OR scientific notation and sig figs = 8.90x103g/mL
A 100 mL graduated cylinder is graded in divisions of 1 mL giving results which have 2 significant figures. Cylinders for measuring up to 10 mL to have divisions at 0.1 mL, so again giving 2 sig figs.2 digits. .
90. mL NaOH, remember there are two sig figs in this problem not one, hence the decimal point after the 90.
136 g x 1 ml/8.58 g = 15.85 ml = volume of the piece of brass.According to Archimedes, this will displace an equal volume of water. Thus, the final volume in the cylinder will be 50.0 ml + 15.85 ml = 65.85 ml = 65.9 ml (to 3 sig. figs.)
1 mole of MgCl2=95.21 grams (found on the periodic table) 17.5 g of MgCl2(1mole of MgCl2/95.21g of MgCl2)=.184 moles of MgCl2(grams cancel out and rounded to 3 sig. figs) .184 moles of MgCl2 (1 Liter/2.5 moles of MgCl2)=0.735L of MgCl2 (moles cancel and rounded to 3 sig figs) 0.735 L of MgCl2(1000 milliLiters/1 Liter)=73.5 mL of MgCl2 and round the answer to 2 sig figs which equals 74 milliLitersof MgCl2
what the density of an object with a mass of 20 grams and a volume of 3 ml?
