Molarity = moles of solute/Liters of solution
Liters of solution = moles of solute/Molarity
Liters NaOH = 3.25 moles NaOH/2.5 M NaOH
= 1.30 Liters NaOH
=============
Molarity = moles of solute/Liters of solution
1.5 M KOH = 3.0 moles KOH/Liters
Liters = 3.0 moles KOH/1.5 M KOH
= 2 liters
or
= 2000 milliliters
Molarity = moles of solute/Liters of solution
1.5 M KOH = 3.0 moles KOH/volume
= 2.0 Liters
A volume of 3,42 L contain 1,9 mol NaOH, with a concentration of 0,555 M.

An alpha particle is emitted when Pt-190 decays to Os-186. An alpha particle has a mass number of 4, and an atomic number of 2. When Pt-190 decays to Os-186, the mass number drops by 4, showing that an alpha particle is emitted, along with energy. The other form of particle that could be emitted is a beta particle, which has a mass number of 0. The difference between 190 and 186 is 4, thus showing the emission of an alpha particle.

heat of vaporization for isopropyl alc is 159 cal/grams
The bromine diatomic molecule has a bond energy of 190 kilojoules per mole. This translates to a bond length of 228 picometers.
Diamonds are produced, at depths of 140 - 190 km beneath the Earth, and it is hot there. They are believed to grow slowly. And they are very very old - perhaps a few billion years. They are bought up from these depths when there is a local volcanic eruption of a particular type. But man-made diamonds are obviously quite new, and they are the equal of natural stones.
density = mass / volume =190 / 20 =9.5g/cm3
Because d=M/V: d= 190/20= 9,5 g/cm3.
As given the question has no solution. The base area cannot be 180 cm since that is a linear measure, not a measure of area, which should be in square centimetres. If it is assumed that the base was 180 SQUARE cm, then Volume = Base*Height So Height = Volume/Base = 190/180 = 19/18 = 1.0555 cm.
203.3= 190 + (7%/100% * 190)= 190 + (7/100 * 190)= 190 + (0.07 * 190)= 190 + (13.3)= 203.3
190 + 190 = 380
You cannot. Cubic centimetres are a measure of volume and I can have a jug containing 190 cc of water. A horsepower is a measure of energy and there is no specific energy in the 190 cc of water (other than that givem by Einstein's e = mc2) and in that case, I could replace the water by 190 cc of air - different mass so different energy. The point is, you cannot convert.
Answer: 187 rounded to the nearest ten is 190.
20% of 190= 20% * 190= 0.2 * 190= 38
17% of 190= 17% * 190= 0.17 * 190= 32.3
60% of 190= 60% * 190= 0.6 * 190= 114
11% of 190 = 11% * 190 = 0.11 * 190 = 20.9
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)
