Known as the "Potato King of the World" by 1902, Groves optimized potato growth methods, out-producing anyone else in the world to that point. His vast financial success—analyzed further in Booker T. Washington's The Negro in Business (1907)—was utilized to help combat racism by providing economic opportunities for other black Americans.
Because a dalton, a unit commonly used to measure atomic mass, is exactly 1/12 of the mass of a carbon-12 atom, this definition of the mole entailed that the mass of one mole of a compound or element in grams was numerically equal to the average mass of one molecule or atom of the substance in daltons, and that the number of daltons in a gram ...
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement. It is the only system of measurement with official status in nearly every country in the world, employed in science ...

By 1950, it was the world's largest toy manufacturer. Marx was also first to mass-produce mechanical toys in the U.S., and many of his early wind-ups are valued collectors’ items. 2 Merrill L. Hassenfeld (1918–1979) Built Hasbro into a leading manufacturer of playthings from a maker of school supplies. He started with a line of doctor and ...
Born Ushijima Kinji (牛島謹爾) in Kurume, Fukuoka, Japan, [5] he entered a preliminary course at the Tokyo Commercial School (now Hitotsubashi University), but failed the entrance examination for the regular course.
Let x be the new total mass of the potatoes (dry + water). Let d be the dry mass of the potatoes and w, the mass of water within the potatoes. Recall w is 98% of the total mass, that is, w = 0.98x. Therefore, x = d + w = d + 0.98x, i.e., x = d / 0.02 = 50 kg. In our case, d = 1 kg so the new mass of the potatoes will indeed be 50 kg.
