Shazia Khan Fbi, i would like to report a case. Holly Wade Divide the grams by the molecular weight of Fluorine to get the amount of moles. Then multiply with Avogadros number (particles per mol). Gabriel Bereta You need 2 formulas: n=m/M and N=Na*n So n is 8.5g / (2*19g/mol) = 0.224 mol which is 0.224 mol * 6.022*10^23 particles/mol = 1.34*10^23 Particles Tracy Ross Fluorine's atomic weight is 18.99 a.m.u. so that means a mole of fluorine weights around 9.5g, a mole contains 6.02214076×10^23 particles inside of it, so half a mole contains 3.0110704 x 10^23 particles Chantelle Reid Was goin to answer but i arrived to late Shqipe Llugiqi This is high-school chemistry, so I do hope you arent like 30 Sharon Peters No wonder she can't do it, it's written in flamgewehr Becca Sisson You could easily find this on youtube... Mehboob Ahmad dont use just use the g/mol ...? Zulam Rama 9,5 / 19 * 6,02E23 2 g 2 x 6,02E23 Sonni Hill Check the weight of Fluor atoms Angela Williams Do your own homework. Jessie Ann Dude I hope you are underage as well Fre Man A lot. Kypriani Thoma She needs to convert the mass of fluorine into moles, which the unit that measures the nb of particles. For that she needs the molar mass, wich can be found easily on google, and divide the mass by the molar mass. Then qhe has the nb of moles, and you can google the nb of particles in one mole Get link Facebook X Pinterest Email Other Apps Comments
