The correct option is A, as Europeans found a great diversity of cultures when they explored Africa. The continent was home to thousands of ethnic groups and languages, highlighting its rich cultural heritage. This diversity significantly influenced European interactions with African societies during exploration and colonization.

Jawaban:1. (a) Jumlah partikel NaCl = 0,1 mol x 6,022 x 10²³ partikel/mol = 6,022 x 10²² partikel (b) Jumlah ion Na⁺ = 0,1 mol x 6,022 x 10²³ ion/mol = 6,022 x 10²² ion (c) Jumlah atom klorin = 0,1 mol x 6,022 x 10²³ atom/mol = 6,022 x 10²² atom 2. (a) Mol urea = massa / massa molar = 0,06 g / 60 g/mol = 0,001 mol (b) Jumlah partikel urea = 0,001 mol x 6,022 x 10²³ partikel/mol = 6,022 x 10²⁰ partikel 3. (a) Mol senyawa tersebut = 3,01 x 10² molekul / 6,022 x 10²³ molekul/mol = 5,00 x 10⁻² mol (b) Massa senyawa tersebut = mol x massa molar (Mg(OH)₂) = 5,00 x 10⁻² mol x 58,3 g/mol = 2,92 g (c) Jumlah ion hidroksida = 3,01 x 10² molekul x 2 (dari Mg(OH)₂) = 6,02 x 10² ion OH⁻
