There are 1,000m is 1k. So just move the decimal one position right. 127.56m
There are 10,000cm in 1k. Move the decimal two positions right. 1275.6cm
Chemical property is when it's observed during a reaction in which the chemical composition or identity of the substance is changed. physical properties is when properties that do change the chemical nature of matter.
example for this is smell, color, freezing point, etc.

Looking at the formula, 1 mole of KIO3 and 5 moles of KI will react and produce moles of iodine molecules or 6 moles of iodine atoms. So first, determine the number of moles of KIO3 and KI provided
moles KIO3 = 0.0121 * 0.097 = 0.0011737 mol
moles KI = 0.0308 * 0.017 = 0.0005236 mol
The limiting reactant is KI at 0.0005236 mol so divide by 5 and multiply by 6 to get the number of moles of iodine atoms.
0.0005236 / 5 * 6 = 0.00062832 mol
Lookup the atomic weight of iodine which is 126.90447
And multiply that by the number of moles of iodine produced
126.90447 g/mol * 0.00062832 mol = 0.079736617 g
Rounding to 4 decimal places gives 0.0797 g</span>
A rectangle box measures 6.00 in. in length, 7.00 in. in width, and 8.00 in. in height. The volume of the rectangular box is 5.506 L
Given,
1 inch = 2.54 cm
Length = 6.00 inches = 6.00 x 2.54 cm = 15.24 cm
Width = 7.00 inches = 7.00 x 2.54 cm = 17.78 cm
Height = 8.00 inches = 8.00 x 2.54 cm = 20.32 cm
Now,
Volume of rectangular box = Length x Width x Height
= 15.24 cm x 17.78 cm x 20.32 cm
= 5506.05 cm3
= 5506.05 mL (\small \because 1 cm3 = 1 mL)
= 5.506 L (\small \because 1000 mL = 1 L)
Hence, the volume of rectangular box is 5.506 L.
