How many moles are there in 987 grams of Ra(OH)2? id also love to know the simplest equation for converting moles --> so i co
OlgaM077 [116]
Mole = \frac{mass}{molar mass}

Mass of Radium Hydroxide = 987g
Molar Mass of Ra(OH) _{2} = ((226) + (2 * 16) + (2 * 1))
                                            =  260 g / mol

∴  Moles of <span>Ra(OH) _{2} = </span>\frac{987 g }{ 260 g / mol }
                                            = 3.796 mols

Satellites equipped with ultraviolet telescopes gather data about galaxies .<br><br> TRUE OR FALSE?
Anna71 [15]

Answer:

True.

Explanation:

Here is an example: Hubble Space Telescope's launch in 1990 sped humanity to one of its greatest advances in that journey. Hubble is a telescope that orbits Earth. Its position above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes.

Hubble is one of NASA's most successful and long-lasting science missions. It has beamed hundreds of thousands of images back to Earth, shedding light on many of the great mysteries of astronomy. Its gaze has helped determine the age of the universe, the identity of quasars, and the existence of dark energy.
