For this you need the atomic (molecular) mass of C12H22O11. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel. C12H22O11= 342 grams
.105 moles C12H22O11 × (342 grams)= 35.9 grams C12H22O11

I don't know. I'm trying to figure that out too.
The number 46313 rounded to 1 significant figure is 50000. The significant digit is 5, so the number is rounded up to the nearest power of 10.
The molar mass of benzene (C6H6) is approximately 78 grams per mole. This is calculated by adding up the atomic masses of carbon (12.01 g/mol) and hydrogen (1.01 g/mol) in the compound.
The chemical formula of lithium phosphide is Li3P.

The formula for sucrose is C11H22O11. To figure this out, you need to list the elements in the compound along with the amount of times it is in the compound and the atomic masses of the elements, like so... Carbon 11 12 132 Hydrogen 22 1 22 Oxygen 11 16 176 Add the right column all up and you get 330. So, to reiterate, sucrose has a molar mass of 330 to the nearest gram.
The molar mass of sodium carbonate to the nearest gram is 105,99 g.
The molar mass of benzene is 76,11 g.
Sucrose: C12H22O11Formula Weight: 342.3Carbon: 12 * 12.01 g/mol = 144.12144.12/342.3 = 42.10% CarbonYou can always check the other elements to double check:Hydrogen: 22*1 = 2222/342.3 = 6.4% HydrogenOxygen: 11*16.01 = 176.11176.11/342.3 = 51.44% Oxygen
Rounding a number to the nearest significant figure means rounding it to the nearest digit that indicates the precision of the measurement. This typically involves looking at the significant figures in the number and rounding to the appropriate level of precision. For example, 345.678 rounded to the nearest significant figure would be 300.
0.01
2,387
That figure is ALREADY rounded to the nearest hundredth !
The answer will depend on the figure - details of which you have chosen not to share.
To find the area of a figure, you first need to identify the shape and use the appropriate formula. For example, for a rectangle, you multiply the length by the width, while for a triangle, you use the formula ( \frac{1}{2} \times \text{base} \times \text{height} ). After calculating the area, round the result to the nearest tenth of a unit for your final answer. Always ensure your measurements are in the same units before performing the calculations.
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". As we are rounding to the nearest hundred then the first figure to be discarded is 9. As this is greater than 5 then the previous figure (3) is increased by 1 (to become 4) 1396 to the nearest 100 is 1400.
