Asweetened ice tea beverage of 355ml contains 43.0 g of sucrose (sugar). calculate the molarity of sucrose in the drink. sucrose: c12h22o11 molar mass kf sucrose= 342.3 g/mol

Hey there!:

Molar mass sucrose = 342.3 g/mol

Number of moles:

n = m / mm

n = 43.0 / 342.3 => 0.1256 moles of sucrose

Volume in liters of solution:

355 mL / 1000 => 0.355 L

Therefore:

M = n / V

M = 0.1256 / 0.355

= 0.353 M

Hope that helps!

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
