1 A silicon chip used in an IC of microcomputer has a mass of 5.68 mg.How many silicon (Si) atoms are present in the chip?2 Calcium carbonate (CaCO3),also called calcite,is the principal mineral found in limestone,marble,chalk,and pearls.(a) Calculate the molar mass of calcium carbonate.(b) A certain sample of CaCO3 contains 4.86moles.What is the mass in grams of this sample?What is the mass of the CO32- ions present?3 Determine the empirical and molecular formulas for a compound that gives the following percentages on analysis in mass percentage.The molar mass is known to be 98.96 g/mol.71.65% of Cl,24.27% of C,and 4.07% of H
1a。是说碳酸盐里钙多少模(molar)
是说现在有4.8模的碳酸盐CaCO3的样本 这个样本里有多少克碳酸盐 还有CO32-的的分子质量数
71.65% Cl,\x0924.27of C,and 4.07%的H这些判断有什么化合物 已知98.96 g/mol这个单位
电脑中硅芯片共计5.68 mg 求硅芯片中硅原子的数量
大致稍微翻译了下。

1 [5.68/(28.0855*1000)]*6.02*10^23=0.00121748*10^23
2 a 100g/mol(是求碳酸钙摩尔质量.翻译出错)
b 486g 291.6g
3 C2H4Cl2

这………………看不懂怎么解

兄弟你去问专业课老师吧,
