1000000000000000 grams
First convert all to the same mass unit, say grams(g) 750,000 g (=750 kg) 400 g 200 g Add the three terms. 750,600 g ( = 750.6 kg)
It depends entirely upon how large the board is - you can make one any size you want!
well the volume of the board is 5.54*10.6*199 = 11686.076 cubic cm. and this volume of board weighs 2860 grams. Thus 1 cubic cm of the board would weigh 0.245 grams so the density is 0.245 g/cc
Either can be used, but grams would be the most practical.
In general, a men's javelin weighs in at 800 grams and a women's javelin at 600 grams. This is not true across the board. Some rules organizations vary allowed weights by the thrower's size and age.
The mass of an apple could be 200 grams, never 200 kilograms. An apple with 200 grams of mass would weigh 1.96 newtons (7.1 ounces) on Earth. If an astronaut carried the same 200 grams with him to a different place, it would have a different weight there.
1.33 grams of oxygen is carried by each gram of normal healthy hemoglobin.
It should be 160g. It means 160 grams of flour which has been sifted to remove lumps and to aerate the flour. 160 grams is approximately 5.6 ounces.
In this case.......... Density = mass in grams/centimeters cubed 5.54 cm * 10.6 cm * 199 cm = 11686.076 cm^3 Density = 28.6 grams/11686.076 cm^3 = 0.00245 grams/cm^3
A spatula would be used to remove 0.25 grams of a solid material from a reagent bottle.
According to the California Raisin Marketing Board at www.calraisins.org/professionals/health/faq_nutrition.cfm: 1 cup of fresh grapes weighs 126 grams; therefore, one quart of grapes, which equals 4 cups, would weigh (126x4) 504 grams.
